Abstract
The effect of impurity Mg and Ca atoms on the optical breakdown threshold of a nonlinear ZnGeP2 crystal at a wavelength of 2.097 μm is studied. An impurity was introduced through diffusion doping by sputtering on a ZnGeP2 substrate followed by annealing in vacuum at a temperature of 750°C for 200 hours. Mg atoms introduced into a single crystal increase the optical breakdown threshold by 31%. When ZnGeP2 is doped with Ca atoms, the opposite trend is observed. The changes in the optical breakdown threshold are suggested to occur due to the creation of additional channels for energy dissipation of radiative and fast nonradiative relaxation processes through impurity energy levels. This suggestion requires experimental confirmation. An increase in the optical strength of ZnGeP2 could expand the scope of its applicability.
期刊介绍：
Atmospheric and Oceanic Optics is an international peer reviewed journal that presents experimental and theoretical articles relevant to a wide range of problems of atmospheric and oceanic optics, ecology, and climate. The journal coverage includes: scattering and transfer of optical waves, spectroscopy of atmospheric gases, turbulent and nonlinear optical phenomena, adaptive optics, remote (ground-based, airborne, and spaceborne) sensing of the atmosphere and the surface, methods for solving of inverse problems, new equipment for optical investigations, development of computer programs and databases for optical studies. Thematic issues are devoted to the studies of atmospheric ozone, adaptive, nonlinear, and coherent optics, regional climate and environmental monitoring, and other subjects.
